Technically there is some risk but I think the blast radius, if present, is extremely small.

`C_INCLUDE_DIRS` is not recognized by GCC.

If I use https://sourcegraph.com/search?q=context:global+%5CbC_INCLUDE_DIRS%3D+-f:clang/&patternType=regexp&case=yes&sm=1&groupBy=repo to find the use cases, one project has a use like add_opt C_INCLUDE_DIRS=$C_INCLUDES, but the search patch seems likely redundant.
